Question Analysis
This question tests the student's ability to determine the constant of variation, , for a direct variation function given two points on the line. The key is to recognize that the line passes through the origin and to use the given point to find the slope, which is the constant of variation.

Key Concept Explanation
A direct variation function has the form , and its graph is a straight line passing through the origin. The constant of variation can be found using the ratio of the y-coordinate to the x-coordinate of any point on the line (except the origin).

Step-by-step Solution
1. Identify the given points: and
